Atomic Edge analysis of CVE-2025-49050 (metadata-based):
The Lead Capturing Pages WordPress plugin version 2.5 contains an authenticated SQL injection vulnerability. This flaw allows attackers with subscriber-level access or higher to execute arbitrary SQL commands. The vulnerability stems from insufficient input sanitization in a plugin endpoint, enabling data extraction from the database.

Atomic Edge research identifies the root cause as improper neutralization of special elements in an SQL command (CWE-89). The vulnerability description states insufficient escaping on user-supplied parameters and lack of sufficient preparation on existing SQL queries. This indicates the plugin likely constructs SQL queries by directly concatenating user input without using WordPress’s `$wpdb->prepare()` method or proper escaping functions. These conclusions are inferred from the CWE classification and vulnerability description, as no source code diff is available for confirmation.

Exploitation requires an authenticated attacker with subscriber privileges. The attacker would send a crafted HTTP request to a vulnerable plugin endpoint, injecting SQL payloads through a specific parameter. Based on WordPress plugin patterns, the attack vector is likely an AJAX handler (`admin-ajax.php`) or a REST API endpoint. The payload would append UNION SELECT statements to extract sensitive data like user credentials, plugin settings, or other database contents. The CVSS vector indicates no user interaction is required for successful exploitation.

Remediation requires implementing proper input validation and parameterized queries. The plugin should use WordPress’s `$wpdb->prepare()` method for all SQL queries incorporating user input. All user-supplied parameters must be validated against expected data types and escaped using appropriate WordPress sanitization functions. The fix should also implement strict capability checks to ensure only authorized users can access database operations.

Successful exploitation leads to complete database compromise. Attackers can extract sensitive information including WordPress user credentials, personally identifiable information stored by the plugin, and other application data. This enables credential theft, privilege escalation, and potential site takeover. The CVSS score of 6.5 reflects the high confidentiality impact combined with low attack complexity and authenticated access requirement.
